Do you recommend me to use an 18650 Ultrafire battery or better choose a superior quality like 18650 EagleTac?

I ordered the two pack of the ultra fire, good lifetime and great quality. I don't suspect you'd notice the difference, so I recommend the ultra fire.

The Ultrafire battery has worked well for me, personally I wouldn't see the need for buying another brand. But choose whatever you will be most comfortable with.

dude, i use these in my flashlights, they are ok but yes they are low drain they stink if your going for mech mod's. but i've had to buy plenty of these for my lights but if it's for your lights try the ultrafire, 3.7V 5000mAh they work amazing and last forever. also they are low drain batteries and they are yellow.

Not sure about the the C rating on these Ultrafires. I've got two sets that I use in two Klarus XT10 LED flashlights putting out 800 Lumens - I get about 1.5 to 2.0 hours on high from each battery. The bottom line: if you're using a similar flashlight for patrol where you need the light for up to several hours during a shift - consider a more expensive battery. For utility or homeowner use I recommend the UltraFires and will buy them again. I have had very good luck over the past two years with them.

I recommend the Orbtronic 3,400mAH 18650 rechargeables and the Intellicharger i4 version 2. The Orbs are quality Japanese parts batteries and all 6 of mine charge to exactly the same 4.7 voltage every time and they seem to last forever. The Orbs are also have been rated top marks and fit this flashlight well. Keeppower is the only other one that is about as good IMHO.

I have used 2 different batteries. Klarus 2200mah and an eagletac 3100mah. Both have about the same results and last 2 1/2 to 3 hours on the highest setting. The klarus 2200mah will not be as bright as the eagletac but will give you about 3 hours, and the eagletac will be slightly brighter but gives you about 2 1/2 hours. It's not a problem for me since I carry extra batteries. Is it worth it???? Definitely!!! Best flashlight I have ever owned...I have 2 of them. Keep in mind that these numbers are on the highest setting... you can still drop to medium and low after a few hours.

Matt, Buy the Trustfire 26650s if this is the 7 or 11 led torch. I own the 7 @ 8500 retina melting lumens. It will work on 2 or 3 18650s or 26650s. I use 3 26650s an they last hours on high. This beast lights up a whole acre! Don't forget to get the universal battery charger.Steve

If you are interested in a flashlight that will last a long time before having to be recharged, then look for those that use the 26650 batteries - either one, two or three (with an extension tube). Too many 18650 batteries with the UltraFire name are counterfeit.

Every mmod is made different. I have 3 mods and one fits snug the other fits loose and one still rattles a bit on a connection. Its just the way they are due to them being un regulated. If you want a sucure snug fit every time, get a variable voltage box mod that has a battery tray made for the 18650 batteries.

I purchased 3.7V 18650 3000mah Rechargeable Batterys. They seem to work well. I've used them for about a year so far.

I own UltraFire and Tenergy Brand of 18650@3000ma. I have 5 set of them. I only had 1 bad one that won't hold a charge in storage. The rest seem fine I measure the voltage on them to check. After a fresh charge it measure 4-4.3 volts. Then it drop to 3.8,4.1 for over about 2 month. I think like everything a little luck is involve. I read the other peoples reviews and 4-2 stars to me if the price is right I'll take a chance. So far it a good deal Beside they are all made in CHINA no matter which brand. The Trustfire charger works fine too. Voltage on batteries checked before this reply...

18650 type. Get some quality batteries like Sony VTC5's, avoid any of these you can see on amazon called Ultrafire or anything like that.

1 Ultrafire(but search other companies i'm sure there are better ones) 14500 1200mAh 3.7v Li-Ion. that's the one i got, i get a good hour on them.

it use UltraFire BRC 18650 3.7V "4000mAh" Li-ion Batteries Battery or any of these batteries: 18650 4000 mAh 3.7V Li-ion Rechargeable Battery. This is a amazing high lumen cree, but the battery consumption is high.

The best batteries in my opinion are the SureFire 123A lithium 3 volt batteries, They are very reasonably priced. I have another make of flashlight that came with a well-known brand of batteries and I replaced them with the SureFire batteries. The beam was much brighter.

I have several 18650 batteries. They are all the red UltraFire batteries, but I'm sure they would be the same size as yours. The single red UltraFire 18650 battery is too long and too narrow for this flashlight. At least the "AAA" batteries it takes are easy to find.

No. Gotta say, the associated batteries are unbeatable. 18650's are the best.

you definitely want the 18650 battery. Less expensive in the long run but more importantly it is a 3.7 volt so you get more juice out of it, brighter light. I NEVER use AA or AAA if there are other options.
